First Claim
Patent Images
1. A method of treating a sphincter, comprising:
- providing a catheter means and an energy delivery device means coupled to the catheter means and including a tissue piercing distal end;
introducing the catheter means into an esophagus;
piercing a sphincter exterior surface with the energy delivery device means tissue piercing distal end;
advancing the energy delivery device means tissue piercing distal end a sufficient distance in an interior of the sphincter to a tissue site; and
controllably delivering energy to the tissue site and create controlled cell necrosis of the sphincter to reduce a frequency of sphincter relaxation.

Abstract
A method of treating a sphincter provides a catheter means and an energy delivery device means coupled to the catheter means. The energy delivery device means has a tissue piercing distal end. The catheter means is introduced into an esophagus. A sphincter exterior surface is pierced with the energy delivery device means tissue piercing distal. The energy delivery device means tissue piercing distal end is advanced a sufficient distance in an interior of the sphincter to a tissue site. Energy is controllably delivered to the tissue site. Controlled cell necrosis is created in the sphincter to reduce a frequency of sphincter relaxation.

47. A method of treating a sphincter, comprising:
-
providing a catheter means and an energy delivery device means coupled to the catheter means, the energy delivery device means including an energy delivery surface means sized to be distanced from a tissue surface of the sphincter while controllably delivering energy to the sphincter; introducing the catheter means into an esophagus; distancing the energy delivery surface means from a selected tissue surface of the sphincter; and controllably delivering energy to the sphincter and creating controlled cell necrosis of the sphincter to reduce a frequency of sphincter relaxation. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)
